13 Inhibiting Gating for Unwanted Sounds MaxBus attempts to activate only one microphone per soundsource. Muting a microphone channel prevents its audio fromappearing at the mixer’s output. However, the muted micro-phone still communicates with other mic channels via Max-Bus. A sound source picked u...
